Ohio’s spike in deer ticks raises Lyme concerns

The state is seeing a shocking increase in the number of deer ticks that can carry Lyme disease, prompting concerns that it will lead to more cases of the illness, insect experts said Wednesday.

A group that includes the state health and wildlife agencies is working to sort out what risks may be posed by last year’s spike in confirmed deer ticks, also known as black-legged ticks, and how best to spread the word and keep people safe. The experts believe the higher numbers are a sign of tick population growth, not simply the result of more active searching last year.

It’s unclear what spurred the increase, though researchers suspect one factor is favorable weather conditions that helped more of the tick population survive and thrive.
